A team that already has or has found its best performance will of course not need many more changes so that it spends a lot of money in the transfer market, in contrast to a team that has not yet found its best performance or is currently developing, they will spend a lot of money in the transfer market and that is normal. Previously Liverpool and Manchester City also spent quite a lot of money in the transfer market.
Klopp built Liverpool from the moment he arrived, there is a character attached to the team with Klopp, I see it as similar to Man United and previous coach Alex Ferguson.
So Klopp's departure will of course create something missing in the Liverpool team that will be difficult to find again.
Usually we have good funds for teams in Premier League to spend and having good depth into their squad even in case of any serious injury or other problem they need to have things well under control so spending huge funds are never been problem for them while they are having enough sources and never try to stay on below then average recently we are having good spending from the few clubs which are trying to settle things with Manchester City and Liverpool are having enough quality and Arsenal is also having better results in last two seasons which helping them for no do too much activity in transfer market.
No doubt now due to departure of Jürgen Klopp things are having some changes but most chances they will keep their squad, and then we will have next season busier for them while Arne Slot is also trying to have faith into this squad which is essential.
